Sparkling point diamonds for a great value! The appearance of this straw cup is absolutely eye-catching. The double-layered body of the cup is meticulously embellished with sparkling rhinestones, which are as bright as the stars in the night sky. Each rhinestone is carefully selected, uniform in size and firmly set, emitting a fascinating radiance under the refraction of light. The diamonds are well crafted and arranged in an orderly manner, outlining stylish and elegant lines, making the whole cup instantly full of luxurious texture. Whether placed on the desk or carried out, can become the focus of attention, highlighting your distinctive fashion taste. Double-layer structure, heat preservation and cold preservation The double-layer design not only enhances the colour value, but also has practical functions. The heat-insulating layer in the middle can effectively block the heat transfer, which is particularly effective in keeping the cold. Loaded with cold drinks, it can keep the temperature low for a long time, allowing you to drink cool at any time in the hot summer. Whether it's an ice-cold juice, soft drink or refreshing iced coffee, the best taste can be maintained in this small cup. At the same time, for warm drinks can also play a certain role in insulation, to meet your different drinking needs. High-quality materials, safe and worry-free In terms of material, the outer layer is made of sturdy and durable high-quality plastic, which is wear-resistant and can easily cope with the bumps in daily use. The inner layer is made of food-grade stainless steel, which is safe, non-toxic, corrosion-resistant and rust-resistant, ensuring the purity and hygiene of drinks. The part of the straw that comes into contact with the lips is made of soft silicone, which is skin-friendly and comfortable, with delicate taste, and easy to dismantle and clean, guaranteeing the health and safety of every drinking water. 601mL - 700mL, just the right capacity The moderate capacity of 601mL to 700mL meets your daily drinking needs without being too bulky and inconvenient to carry. Whether you need to rehydrate during busy work, quench your thirst during outdoor sports, or drink water while shopping or travelling, this capacity is just right. You can fill it with your favourite drinks and enjoy a pleasant drinking time.
